Assuming standard conditions, arrange the following in order of decreasing strength as oxidizing agents in acidic solution: Cr2O2−7,H2O2,Cu2+,Cl2,O2Cr2O72−,H2O 2,Cu2+,Cl2,O2. Rank from strongest to weakest. To rank items as equivalent, overlap them.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

it would be a gas formation
